Kepler Discovers 1,235 Planet Candidates


Define Planet Occurrence:# Planets / # Stars

=


Define Planet Occurrence:

# Planets / # Stars

Signal/noise = Dimming/Uncertainty in Dimming


Define Planet Occurrence:

# Planets / # Stars


Categorize Planets by

Diameter and Orbital Period


Categorize Planets by

Diameter and Orbital Period


Correction for Kepler’s Detection of

Nearly Edge-on Orbits

Diameter of Star

Probability of Transit = -----------------------------


Correction for Keplers Detection of

Nearly Edge-on Orbits

Diameter of Star

Probability of Transit = -----------------------------

2 x Orbital Distance


Categorize Planets by

Diameter and Orbital Period



Correct for Inclined Orbits

Accounting for 13

Planets in inclined orbits


Correct for Inclined Orbits

Accounting for 8

Planets in inclined orbits


Define Planet Occurrence:

# Planets / # Stars


Number of Kepler Target Stars

Amenable to Planet Detection in Each Category

Typically

58,000 stars


Define Planet Occurrence:

# Planets / # Stars


Define Planet Occurrence:

# Planets / # Stars

Compute in each
